ABSTRACT

Study Design: Retrospective study. Objectives: The purpose of this study was to gassess gln-llgnmnnlnl mm-the effect of saittaspiopevic aignmetothe ciicasyptosof thoracolumbar kyphosis (TLK; T10-L2 Cobb’s angle >20°) inosteoporotic patients. Summary of Literature Review: Few studies have investigated the clinicalsymptoms and radiologicalfeatures of TLK caused by de­generative changes. There is also controversy over whether clinicalsymptoms willdeteriorate inpatients with TLK or which treatment should be chosenaccordingto the degree of TLK. Materials and Methods: FromMay 2005 to May 2016, we reviewed 75 patients who were diagnosed with TLK (T10-L2 Cobb’s angle >20°) and osteoporosis. Patients were excluded fromthe study if they had neurologicalsymptoms, underlyingspinaldisorders, or unstable vertebralfractures. Fifty patients with TLK due to anosteoporotic vertebralcompressionfracture (group F) and 25 patients with senile TLK (group S) were assessed by clinicalsymptoms and radiologicalparameters. Thoracolumbar kyphosis angle and sagittalverticalaxis (SVA) were also analyzed. Clinicalsymptoms were assessed usinga visualanalogue scale (VAS) and the Oswestry Disability Index (ODI). Results: There were no significant differences inclinicalsymptoms (VAS, ODI) and radiologicalparameters betweengroups F and S, or accordingto the degree of -33-44lnl mmgnnlmn ngl ml-TLK (20°-30°, 0°-40°, >0°). Ciicasyptoswere significatyore severe ipatiets with saittaibaance (SVA >5 cm) thaninthose with sagittalbalance. Conclusions: Sagittalimbalance is a more important factor affectingclinicalsymptoms thanthe cause or the degree of TLK. Therefore, sagittalimbalance should be considered inthe management of TLK inosteoporotic patients. Key Words: Thoracolumbar kyphosis, Osteoporosis, Sagittalspino-pelvic alignment, Sagittalimbalance
